Benefits of High Definition

Benefits of High Definition

Ultimately, your image quality with high definition cameras will be much greater than that with standard definition. Here we explain how.

For any given angle of view, the increased pixel density not only increases the identification distance of the camera but also the width of the image at the point you can identify a person.

As a guide, keeping the pixel density the same, you will be able to approximately double the identification distance of a camera.

With standard definition D1, you can identify a person at the point your image width is a little over 10 feet. With high definition, that increases to a little over 25 feet. Using high definition cameras, this is actually more than double the width because of the change in aspect ratio. The ratio for D1 is 3:2. 1080p is 16:9 widescreen.

Look out for the competition who report image quality that is 6 times better than D1. They claim this as there are 6 times as many pixels however that really is meaningless in the real world. To put a number on it, taking into account the increased resolution and the additional image width, high definition images are twice as good as standard definition.

How much better really is High Definition?

That’s a great question! And the answer is a lot, but not as much as you think!

All the measures of twice as good, or increased pixel density and similar can become overwhelming. Take a look at the images to see exactly how much better the images will be.

Switching from standard definition to high definition allows you to go from this:

Quite a difference we think you’ll agree!

So, that’s how much better high definition is!
